NOS Telefunken RGN2004 full-wave directly-heated rectifier - never used, vacuum fully intact. Large bottle construction with solid gray plates and the Telefunken diamond logo etched on the glass. The plate structure carries the etched "Wehrmacht" military procurement marking; the glass envelope shows the RFV inspection code "BAL 1944" confirming 1944 wartime production. Both diode sections tested strong on the BM-215A. Price per tube.
Please note: Small loose glass particles are present inside the envelope - visible in photos. This is a manufacturing or age-related anomaly. The tube has not lost vacuum, both diode sections test strong, and there is no electrical effect. Fully disclosed for transparency.
